Where rooflight jobs go wrong

Large glass units are heavy, awkward and expensive to replace if dropped. Getting one onto a roof may need a hoist, a crane or a planned lift from a scaffold. Fitting it means setting it level on packers, without twisting the frame, while the weather holds. A general builder may do this a few times a year. A rooflight fitting team plans the lift, the equipment and the sequence before the day. That lowers the risk to the unit and to the people lifting it.

Is your Chislehurst address covered?

Covering Chislehurst properly means covering the whole of it, house or business unit, across BR7, SE9 and DA14. Beyond the town, we take on jobs in Eltham (2 miles) and Bromley (2 miles) as standard. Each one gets the same survey or photo-based pricing, the same written quote, and the same fitting standard.

Planning and building control

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

Questions about rooflight fitting in Chislehurst

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.

What if my roof opening is the wrong size for the rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

What upstand height and roof pitch does rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
